Learning targets are hard to write.
Here's one (of 27) that I used in F'13:
D.3 I can calculate, work flexibly with, and demonstrate understanding of statistical measures of center and spread for numerical data, including: mean, median, MAD, and IQR.
If you tease that target apart, you realize it contains 12 distinct skills: {calculate, work flexibly with, and understand} x {mean, median,
MAD, and
IQR}.
That's a problem: such a complex target is very difficult to assess. Do they have to show all parts on a single task for a proficient score? Can they piece it together over several tasks? If so, how do we keep track?
So I swore off using complex targets for
my Su'13 College Algebra course:
